The original form of trade, barter, saw the direct exchange of goods and services for other goods and services. Barter is trading things without the use of money. Later one side of the barter started to involve precious metals, which gained symbolic as well as practical importance. Modern traders generally negotiate through a medium of exchange, such as money. As a result, buying can be separated from selling, or earning. The invention of money (and later credit, paper money and non-physical money) greatly simplified and promoted trade. Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade.

Trade exists due to the specialization and division of labor, in which most people concentrate on a small aspect of production, trading for other products. Trade exists between regions because different regions may have a comparative advantage (perceived or real) in the production of some trade-able commodity, or because different regions' size may encourage mass production. As such, trade at market prices between locations can benefit both locations.

Trade (nightclub)

Trade was a highly successful, pioneering and influential gaynightclub started in 1990 by Laurence Malice. Trade was unlike any other club at the time as it opened from 4am until 1pm on Sundays at Turnmills, Clerkenwell Road, London. The club was touted as "the original all night bender". The door policy was firm but fair: "You don't have to be gay or a member to get in, but your attitude and look will count".

Early Years 1990 - 1995

Trade quickly grew in popularity as other clubs at the time such as Heaven, G-A-Y and The Fridge closed at around 02:00-03:00 Sunday mornings, an hour or so before Trade opened at 03.00 Therefore, clubbers were able to go straight on to the club.
At the time many guys went cruising in the parks after leaving other clubs. The name 'Trade' and the opening hours was to encourage guys to go to the club as a safer alternative.

Turnmills was the first club in the UK to be given a 24-hour "Music & Dance" licence. This was gained after Laurence Malice had for a long period of time tried to convince Mr Newman that there was a need for people to be able to party in a safe environment after 3am in the morning.
Due to this licensing advantage, the venue's role was crucial to the success of Trade.

(In many programming languages where the swap function is built-in; in C++, overloads are provided allowing std::swap to swap some large structures in O(1) time.)
After swap() is performed, x will contain the value 0 and y will contain 1; their values have been exchanged. Of course, this operation may be generalized to other types of values, such as strings, aggregated data types and comparison sorts, utilize swaps to change the positions of data.

Using a temporary variable

The simplest and probably most widely used method to swap two variables is to use a third temporary variable:

While this is conceptually simple and in many cases the only convenient way to swap two variables, it uses extra memory. Although this should not be a problem in most applications, the sizes of the values being swapped may be huge (which means the temporary variable may occupy a lot of memory as well), or the swap operation may need to be performed many times, as in sorting algorithms.
